عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ إِسْمَاعِيلَ بْنِ مَرَّارٍ عَنْ يُونُسَ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ سَأَلْتُهُ عَنِ الْعَقِيقَةِ أَ وَاجِبَةٌ هِيَ قَالَ نَعَمْ يُعَقُّ عَنْهُ وَ يُحْلَقُ رَأْسُهُ وَ هُوَ ابْنُ سَبْعَةٍ وَ يُوزَنُ شَعْرُهُ فِضَّةً أَوْ ذَهَباً يُتَصَدَّقُ بِهِ وَ تُطْعَمُ الْقَابِلَةُ رُبُعَ الشَّاةِ وَ الْعَقِيقَةُ شَاةٌ أَوْ بَدَنَةٌ .
3. Ali ibn Ibrahim has narrated from his father from ’Isma‘il ibn Marrar from Yunus from abu Basir who has said the following: “I once asked abu ‘Abd Allah, Alayhi al-Salam, about Aqiqah : if it is obligatory. He (the Imam) said, ‘Yes, Aqiqah must be offered for him, his head is shaved when he is seven days old and his hairs are weighed with silver or gold to be given in charity. One-fourth of the sheep is served to al-Qabilah (the special nurse, doctor). The animal for Aqiqah should be a sheep or Badanah (camel of a certain age).”’ ( Al-Qabilah according to hadith number three, chapter ninety-three is a nurse who helps a woman to give birth and also thereafter not the one who helps one to give birth only and then moves away.)
